Chandra X-ray Image of LHa115-N19 (3-color)
Astronomers used Chandra to peer into a region of the Small Magellanic Cloud. This area, known as LHa115-N19 or N19 for short, is filled with ionized hydrogen gas and it is where many massive stars are expelling dust and gas through stellar winds. When the X-ray data are combined with the other wavelengths, researchers find evidence for the formation of a so-called superbubble. Superbubbles are formed when smaller structures from individual stars and supernovas combine into one giant cavity.(Credit: NASA/CXC/UIUC/R.Williams et al.)
